Chat SDK now has an [adapter directory](https://chat-sdk.dev/adapters), so you can search platform and state adapters from Vercel and the community.

These include:

- **Official** adapters: maintained by the core Chat SDK team and published under `@chat-adapter/*`
- **Vendor-official** adapters: built and maintained by the platform companies, like [Resend](https://chat-sdk.dev/adapters/resend) and [Beeper](https://chat-sdk.dev/adapters/matrix). These live in their GitHub org and are documented in their docs.
- **Community** adapters are built by third-party developers, and can be published by one, following the same model as [AI SDK community providers](https://ai-sdk.dev/providers/community-providers).

We encourage teams to build and submit adapters to be included in this new directory, like Resend's adapter that connects email to Chat SDK:

```typescript
import { Chat } from "chat";
import { MemoryStateAdapter } from "@chat-adapter/state-memory";
import { createResendAdapter } from "@resend/chat-sdk-adapter";
const resend = createResendAdapter({
  fromAddress: "bot@yourdomain.com",
});
const chat = new Chat({
  userName: "email-bot",
  adapters: { resend },
  state: new MemoryStateAdapter(),
});
// New inbound email (new thread)
chat.onNewMention(async (thread, message) => {
  await thread.subscribe();
  await thread.post(`Got your email: ${message.text}`);
});
```

Browse the [adapter directory](https://chat-sdk.dev/adapters) or read the [contributing guide](https://chat-sdk.dev/docs/contributing/building) to learn how to build, test, document, and publish your own adapter.
